Had a new boiler install and it's been working perfectly. I was specifically help by David, and was able to answer all my questions clearly. David displayed his expertise and if I ever have any issues with the boiler again I will definitely be a return customer. Thanks guys for your professionalism and amazing work.

I had the pleasure of the Chivalry Plumbing fixing my gas heater problem, and I couldn't be happier with the experience. The office staff was incredibly pleasant and professional making appointment and communicating further, it was smooth and hassle-free. The technician Eric was equally impressively knowledgeable and able to explain the details concisely to a non professional. He was pleasant to work with and also highly professional and accommodating. He listened to my concerns, addressed them promptly, and ensured that everything was done to the highest standard. The attention to detail and commitment to do the best job possible was clear. I highly recommend Chivalry Plumbing to anyone in need of plumbing services. I will definitely use them for any future plumbing and heating needs. Added on 12/8: Chivalry followed up on their repairs a few days after the initial visit and since my main level still did not get heat I asked for a repeat visit from the technician. This time it was Anthony who confirmed we had a problem with thermostat and the faulty valve on the pipe. I did suspect the thermostat problem but it is an ancient manual version (and I would rather keep it vs all these new ones), but I would never figure out the wiring. Happy the thermostat stays :) Anthony was quick and knowledgeable and I FINALLY have heat in the whole house, and very timely as it is freezing outside. Thank you.

I’ve had Chivalry repair a sewage issue and replace the water heater and heating system in my home, and both times they did an excellent job. David and his team prioritized my schedule, worked with me to determine what my home needed, and provided clear options.
